Title: Fuel injection nozzle for an internal combustion engine
IPC: F02M61/12
Filed: 1962-07-10
Abstract: A guide member 38 for a needle valve 33 of a fuel injector is initially a loose fit and is secured to the nozzle body, after the needle has been correctly aligned, by a resin such as an epoxy resin. The lower end of the needle engages a guide face 60 on the nozzle tip 12 and the guide member 38 has threads which loosely engage in a threaded part of the bore of the nozzle body. In assembly, the member 38 is coated with epoxy resin and inserted into the body with the needle 33, which is urged against its seat during assembly by a tool with a spring-loaded plunger. The loose fit of the guide 38 permits the needle 33 to take up its correct position in the guide surface 60 while the resin is still fluid. The injector is then heated in an oven to cure the resin and permanently secure the guide 38 in its correct position and the injector assembly is subsequently completed by the fitting of the loading spring 43 with its adjustable abutment 48 and a valve lift stop 52.

Abstract: The invention relates to penicillins of formula <FORM:1004670/C2/1> and non-toxic salts thereof, where R is alkyl, phenyl, phenyl substituted by chlorine, hydroxy, alkoxy or amino or a heterocyclic group. Specified are a -carboxybenzylpenicillin, a -carboxy - 3 - thienylmethyl penicillin, a - carboxy-p - chlorobenzyl penicillin, a - carboxy - p-methoxypenicillin, a - carboxy - m - hydroxy penicillin, a - carboxy - p - aminobenzyl penicillin and a - carboxy - p - benzyloxycarbonylaminobenzyl penicillin. Typical salts are the alkali metal, aluminium, ammonium and substituted ammonium salts. The penicillins are produced by coupling 6-amino-penicillanic acid, or a salt thereof, with a reactive derivative of an acid of general formula <FORM:1004670/C2/2> where R has the above meaning and X is hydroxy, chlorine or OR1 where R1 is alkyl, aryl, benzyl or substituted benzyl, which is subsequently removed. Removal of R1 is effected by catalytic hydrogenation, where R1 is aryl, benzyl or substituted benzyl. Decarboxylated penicillin analogues formed as impurities may be removed by (a) chromatography, (b) recrystallisation from solvents, (3) degradation to 6-aminopenicillanic acid by means of amidase enzymes. Monobenzyl phenylmalonate is prepared by treating phenylmalonic acid and benzyl alcohol with hydrogen chloride. Monobenzyl phenylmalonate may be converted to the acid chloride by treatment with thionyl chloride. Acid chlorides of phenylmalonic acid, n-butylmalonic acid, 3 - thienylmalonic acid, p - chlorophenylmalonic acid, p-methoxyphenylmalonic acid, p-benzyloxycarbonyl - aminophenyl malonic acid, a - benzyloxycarbonyl - p - benzyloxycarbonylaminophenylacetic acid and m-benzyloxycarbonyloxy phenylmalonic acid are likewise prepared. p - Aminophenylmalonic acid and m-hydroxyphenylmalonic acid are prepared by treating, respectively, p-aminophenylacetic acid and m-hydroxyphenylacetic acid with isopropyl magnesium bromide followed by solid carbon dioxide, and are then treated with benzyl chloroformate to give, respectively, p - benzyloxycarbonylaminophenylmalonic acid and m-benzyloxycarbonyloxyphenylmalonic acid. The mono-acid chloride of the latter is reacted with benzyl alcohol to give a -benzyloxycarbonyl-p-benzyloxycarbonylaminophenylacetic acid. The penicillins have antibacterial properties and may be used for treating infections of men and animals e.g. mastitis in cattle. They may be used as nutritional supplements in animal feeds.

Title: Improvements in or relating to the manufacture of sliding-clasp fasteners
IPC: B29D5/00
Filed: 1969-04-26
Abstract: Two rows of sliding clasp fastener links are produced simultaneously by apparatus comprising a roller 1 with two rows of pins 2, 3 relatively staggered, between adjacent pins of which two filaments 10, 11 are fed by pairs of rollers 4, 5 and 6, 7 respectively. Projections 8, 9 on the rollers 5 and 7 are arranged to flatten the filaments at positions spaced by the length of a link such that when a filament is fed between a pair of pins to meet an abutment pin, the filament will bend at the flattened part. When a link has been formed the roller 1 is moved a distance equal to the pitch of adjacent pins in a row so that each filament is shaped around a pin and is ready to be fed between an adjacent pair of pins. The so formed loops are flattened by a stamper 16 and fed into a heated guide channel for stabilizing the link shape before being removed from the roller. Additional projections 17, 18 are provided on the rollers 5, 7 which engage recesses 17a, 18a in the opposed rollers 4, 6 to form shaped areas in the filaments which, when the loops are flattened create engagement or meshing surfaces for the flattened areas of the other row of links.
